March 7, 1961

I was born 51 years ago today. Weighing in at around 7 pounds, I weighed about as much as my head weighs now.

In March of 1961 CO2 was at 316 parts per million; in March of this year, CO2 will come in around 395 parts per million.

In March of 1961, the top Federal Income Tax Rate was 91 percent of your income; today it is 35 percent.

I was one of 183 million Americans; today I am one of 310 million Americans.

There were 3 billion people living on the planet in 1961; today there are 7 billion people.

I could expect to live 70 years in 1961. So, on average, I have 19 years left.
